Dr. Maureen Thornborrow
Veterinarian
Dr. Maureen Thornborrow graduated from the University of Wisconsin School of Veterinary Medicine in 2003. After growing up in Madison, Dr. Maureen attended the University of South Carolina, where she earned her BS in Marine Science. She returned to Madison to attend veterinary school, where she met her husband, Mark. After graduation, she and Mark moved to Green Bay, WI, where she practiced emergency medicine for several years before moving into general practice. After owning and eventually selling their own practice, she and Mark moved to the Northwoods with the intention of retiring but found she missed the animals and medicine too much to stay away. Dr. Maureen especially enjoys veterinary dentistry, internal medicine, and preventative care. When not working, she enjoys snowmobiling, fishing, hunting, and hanging out with her two Dogue de Bordeaux, Rubi and Monty.

He has enjoyed practicing veterinary medicine for Northwoods Animal Hospital after joining the team in 1987. He appreciates the multiple facets that general practice offers, with particular interests in ophthalmology, soft tissue surgery, and preventative medicine. Dr. Dave and his wife, Audrey, have three children, and they all enjoy the year-round outdoor activities the Northwoods offers.

Deb grew up in Minnesota and moved to the Wisconsin Northwoods in 2009. She graduated from Argosy University in 1994, a fact that makes her feel old!

Deb is the resident “crazy cat lady,” and her passion is taking in orphan kittens and bottle-raising them. She lives with her husband, a yellow Labrador named Cleo, and two cats, Dennis & Olive. In her free time, she enjoys fishing, bow hunting, quilting, and reading.
Shelley
Client Service Representative
Born in Green Bay, WI, Shelley has enjoyed coming to the Northwoods since 1988. With her love for the outdoors, Shelley and Tom, her husband of 35 years, decided this is where they wanted to retire and build their retirement home in St Germain. Shelley enjoys watching nature’s wildlife, hunting, fishing, going for walks, reading a good book, and spending time at the bowling alley with her husband. After 35 years of office management, her love of animals brought her to Northwoods Animal Hospital, where she is able to help care for your fur babies as if they were her own!
